Well said!
Millions of papers, books and articles have been written, and grotesque amounts of money has been poured into the so-called CRM classes held all over the world. And what have we achieved? Zip. Use the money on better equipment for ATC & pilots, longer/wider runways, more precision approaches, better snow clearance/wx forecasting etc. That would really have helped. CRM is just a bogus term for, like you said, common sense. Those in need of an attitude change arenīt gonna learn anything from sitting in a group of friends/colleagues, discussing whether to bring the booze, shotgun or porn magazine along from the desert/jungle crash.
I havenīt noticed any change in behaviour in anyone from any of the many CRM refresher courses I have attended. Idiot captains remain idiots, and the rest already have a well developed common sense, so why bother with the waste of time and money? If a pilot exhibits "unwanted" attitudes and is incapable of working TOGETHER with his colleague - telle it to his face, give him one more chance, and then out the door if he doesnīt improve. Personalities and character traits arenīt cannot be changed through two hours of playing games in a classroom once a year. There - now Iīve said it.
